The Benefits of a Planar Magnetic Driver
Planar magnetic driver is a type of audio technology that is found in many of the most premium headphones and IEMs. It is a superior technology with numerous advantages that set it apart from other balanced or dynamic armature driver types.
It is crucial to be aware of the disadvantages of
planar magnetic iem drivers. They are a higher price and the need for an amplifier to drive them.
Ultra-thin diaphragms
Every sound we hear, from the loudest crash of a cymbal to the tiniest creak of a piano bench is represented by a complex and turbulent pressure wave. The driver of a top headphone needs to reproduce these waves accurately without omitting any details or distortion of the audio. This requires a lightweight, thin diaphragm that can respond quickly and swiftly to a variety of frequencies.
Planar magnetic drivers use flat diaphragms that are covered with a conductive layer and is able to float between magnets. This allows them to create an even field of magnetism across the entire diaphragm surface, reducing distortion.
This approach, however, introduces additional challenges such as the possibility of membrane resonance problems and turbulent airflow within the grid-like magnetic arrays. These issues could lead to an amplitude of the mechanical resonance frequency of the diaphragm that is several times greater than the input frequency, thus reducing the sensitivity of a voice pressure sensors.
Utilizing a patent-pending technology called "Spherical Acoustic Structure" (SAS), Final was able to overcome these limitations of the D8000 by making use of a single piece material that is both diaphragm and conductor. The idea was built on ribbon speakers that have their spherical conducting, but it was more affordable for headphones because of its size and power requirements.
A ringing sound is another challenge that many
planar magnetic designs have to face. It occurs when high-frequency and low-frequency notes are played. This is caused by a mismatch between force of the magnetic field applied to the diaphragm as well as the natural flexing characteristics of the diaphragm itself.
To solve this issue, Final used an ultra-thin polymer film, also known as Parylene. The material was chosen because of its superior mechanical strength, bending ability and uniform thickness. It also has consistency in thickness. These qualities were essential to ensure that a thin, solid film would stretch without creating unwanted wrinkles or creases.
Superior transient response
The fundamental operation of planar magnetic drivers is similar to traditional dynamic drivers, the method by which they produce sound waves differs. The primary difference is that the conductor of a planar driver is laid out in a flat, 2D pattern on the diaphragm instead of a coil wrapped around a cone-shaped diaphragm. Conductors can react to magnetic fields on both the diaphragm's edges and generate sound waves that are extremely precise. This technology also eliminates the need for a voice coil that could alter its impedance according to its frequency, resulting in a clear, distortion-free reproduction of music.
In addition that, planar magnetic drivers are more durable and lighter than traditional drivers, since they do not have moving parts that can wear out over time. They are also less prone than conventional drivers to distortion, which can affect the audio quality. They have a faster response time and reproduce sounds more quickly.
The large surface area of the diaphragm planar, however it requires more power to move it and create sound waves. These headphones require an amplifier for headphone that can be driven at a suitable level. The additional weight and cost can be a turnoff for certain listeners.
Another advantage of planar magnetic drivers is that they create a wide soundstage, which can be larger than traditional dynamic headphones. This is due to the fact that a large flat diaphragm produces an unidirectional wavefront, rather than the spherical wavefront that is focused typical of dynamic drivers. This is a major characteristic of headphones that planar and gives a full-bodied listening experience.
Audio reproduction that is accurate and natural
Planar magnetic drivers deliver natural and faithful audio reproduction when compared to traditional dynamic driver models.
planar magnetic headphone magnetic drivers create equal magnetic forces by using two rows of magnets, unlike conventional dynamic drivers which have a cone-shaped, curved membrane that is vibrating. The diaphragm is moved in a wave-like motion. This can help to reduce distortion. They can also reproduce music in greater frequency ranges, from the lowest lows to the highest highs. This makes them an excellent option for sound professionals as well as music enthusiasts.
The thin, flexible diaphragm in a planar magnet driver moves faster than a dynamic driver. This allows it to respond to changes in sound signals and produce precise reproduction. Additionally, the absence of a coil positioned behind the diaphragm reduces the likelihood that there will be contact between the mechanical parts that can cause distortion at higher volumes.
This means that the diaphragm has the ability to effortlessly move huge amounts of air to reproduce bass frequencies. The size of the diaphragm and
Planar Magnetic its flexibility are vital for producing the rich bass you hear in your favorite music. Dynamic drivers on the other hand tend to be smaller and stiff, making it difficult for them to withstand the high-speed movements required to reproduce the bass.
Despite their benefits, planar magnetic drivers are not used as much in headphone or IEM products because of the high price and the complexity of their design. This is partly due to the fact that they need amplifiers to be driven. This makes them less portable. Nevertheless,
Planar magnetic they remain well-liked by music lovers and critical listeners who appreciate their outstanding performance and high audio quality.
Wide frequency response
While many headphones and IEMs utilize traditional dynamic drivers that have a cone-shaped diaphragm that moves back and forth to create audio waves Planar magnetic headphones use flat and uniform diaphragms which create sound in a controlled and consistent manner. This produces a wide frequency response that provides accurate and faithful reproduction of music. They are also referred to as having a superior transient response. This means that they can react quickly and precisely to audio signals.
In order to achieve this, they use a planar array of conductors that're spread across a thin diaphragm sandwiched between two magnets. When an electrical signal is transmitted through this array of conductors, it becomes electromagnetic, and interacts with diaphragm magnetic fields to cause the push/pull effect. This allows the diaphragm's magnetic fields to interact with audio signals quickly, resulting in superior sound reproduction.
The low distortion rate is another reason for these drivers to be very well-liked by audiophiles. They can't produce as much harmonic distortion because they don't utilize the same moving parts. They also have a lower resistance and provide an unresistance load to amplifiers. This makes them simpler to drive.
Planar magnetic drivers are used in high-end audio equipment because of their superior performance. However, this means that they are more expensive and require an amplifier, making them less suitable for a grab and go' kind of driver. Audiophiles will sacrifice the additional cost and effort for the high-quality headphones they provide. These headphones are considered the best option for anyone who wants to enjoy a wonderful listening experience.
